Biochem/physiol Actions

Bisphosphonate antiresorptive agent. Less potent inhibitor of farnesyl diphosphate synthase (IC50 = 80 μM) as compared to the nitrogen containing bisphosphonates
Etidronate helps to guard chronic ocular hypertension prompted retinal oxidative stress. It stimulates the development of retinal ganglion cells through insulin-like growth factor 1 (IGF-1) signaling pathway. It may possess neuroprotective effects in in vivo and in vitro rat model of glaucoma. Etidronate belongs to bisphosphonates.

Application

Etidronate disodium hydrate has been used in the synthesis of bisphosphonate derivatives of adenosine triphosphate (ATP)by T4 RNA ligase. It has also been sued to inhibit human farnesyl diphosphate synthase (FDPS).

Bone mineral density response to once weekly delayed-release formulation of risedronate, given before or following breakfast, was non-inferior to that seen with traditional immediate-release risedronate given daily before breakfast. Delayed-release risedronate is a convenient dosing regimen for oral bisphosphonate therapy

Nitrogen-containing bisphosphonates (NBPs) have greater anti-bone-resorptive effects than non-nitrogen-containing bisphosphonates (non-NBPs). Hence, NBPs are the current first-choice drug for osteoporosis. However, NBPs carry a risk of osteonecrosis of jaws. Some animal and human studies suggest that non-NBPs may have anti-bone-resorptive
